Shortly to the northeast is the Benjamin Hawkins Bridge over the Flint River, which marks the Taylor–Crawford county line.

SR 128 heads northeast into Roberta, where it meets its northern terminus, an intersection with US 341/SR 7 (South Dugger Avenue).

is a 1.9-mile-long (3.1 km) bypass route that exists entirely within the south central part of Macon County, along the western edge of Oglethorpe.

It briefly passes through a corner of the town, and curves to the northwest, meeting Jake Smith Road/West Cuyler Street.
